APPARATUS FOR PURIFYING DIRTY WATER.

SPECIFICATION forming part of Letters Patent N 0. 674,017, dated May 14, 1901. Application filed August 14, 1899. Serial No- 72'7,202. (N0 model.)

To all 2117x0122 it may concern:

Be it known that I, HERMANN RIENSCH, a subject of the King of Prussia, German Emperor, and a resident of Uerdingen-on-the- Rhine, in the Province of the Rhine, German Empire, have invented certain new and useful Improvements in Apparatus for Purifying Dirty WVater, of which the following is an exact specification.

This invention relates to a mechanism for purifying dirty industry waters, and has for its object to provide an apparatus by means of which a regular constant work may be attained-that is to say, by means of which the substances accumulated upon the purifyinggrates through which the dirty water flows are removed from the same in order not to stop in any respect the passing of the water. Practice has proved that this is a very diflicult problem to solve by machinery, for the reason that the part located underneath the water surface suffered under the influence of the substances being mixed with dirty industry waters. These substances very often effected a stopping of the grates, so that the water took its way over the top of the grates and a purifying of any kind was not effected at all. To do away with all these drawbacks is the chief purpose of the apparatus forming the subject-matter of my present application.

As a purifying-grate I employ a grate formed by wires fixed in longitudinal direction within a frame arranged somewhat inclined underneath the water surface.

The apparatus essentially consists of rotating elastic combs, which by means of guiderails and guide-rollers are conducted over the grate. These rotating combs raise the dirt accumulated 'upon the grate somewhat over the surface of the water, whereafter it is removed from the combs byasuitable mechanism.

My invention will be fully understood with reference to the accompanying drawings, and the description followinghereinafter, in which drawings similar letters denote similar parts, and in which- Figure 1 shows my apparatus partlyin section and partly in side View. Fig. 2 illustrates a transverse section through line a: a;

of Fig. 1. Fig. 3 illustrates a detail View of the dirt-removing rail. Figs. 4 and 5 represent a mechanism for cutting and removing compact substances, such as tails of beetroot eventually mixed with the water. Fig. 6 is a detail view of the same.

In Fig. 1, a is a tank through which flows the water to be purified. b is a grate consisting of longitudinally arranged wires. This grate is stretched over borders 1) and fixed by means of plugs o Above the tank a shaft 0 is suitably arranged. This shaft 0 carries two telescopic arms d are provided for pressing the arms 61* outward, the outward movement of these arms being determined by screw-bolts f, screwed into the arms 01 and movingin slots 9 of the arms d. The arms d d on their extremities are provided with rails 77?, carrying combs or teeth in form corresponding to the openings of the grate. These combs are not illustrated in the drawings, as they are of too small a size. On the side walls of the tank a guiderails t' are arranged, upon which guide-rails move rollers 10, fixed to the arms (1 When bysuitable means rotation isimparted to the shaft 0, the arms (l' and (1 with their combs h and rollers 7c, traverse the way indicated by dotted lines, the combs moving in a circle until their rollers come to run upon the guide-rails 2'. From the drawings it easily can be seen that when the rollers come to run upon the guide-rail 1) the combs h enter the grate. The elastic arms 62- d are shortened,so that the combs can pass freely through the grate,thereby removing the dirtysubstances accumulated upon the same. These substances remain upon the comb until the same has reached the position indicated in the drawings at the right on Fig. 1, whereafter they are removed upon worms for conducting them away by means of a mechanism described hereinafter. The grate may be of straight or other suitable form. In the example indicated a grate Springs 6 of straight form is employed. The guiderails are somewhat slanting, so that at the center the distance between the rails and the grate is greater than at the extremities of the rails. Thereby the combs enter equally the grate atall places, notwithstanding the combs being placed inclined to the surface of the grate when they enter and when they leave the same,while in the middle position they are directed quite angular to the grate.

In some cases brushes advantageously may be employed instead of combs. When now these latter have reached the position illustrated in the drawings at the right on Fig. 1', the dirt must be removed. To attain this end, use of the mechanism described hereinafter is made.

A shaft 9 has its bearing upon two standardsf, arranged on the side walls of the tank a. A rail 7: is suspended to this shaft 9 by means of two arms 72. The shaft g further carries an arm 7c, which is connected to a double lever m, having its bearing at m. This connection is effected by the connecting-rod Z. A weight 'n is suspended to the free extremity of the lever. In order to counterbalance the weight of the rods, the shaft 9 carries a weighted lever 0. Corresponding to the number of the dirt-removing combs cams 10 are fixed tothe shaft 0. These cams p influence the double lever m at the edge m that is to say, at this edge they raise the lever until under the action of the weight n it falls down again. In order to prevent impacts, a spiral spring q is suitably arranged.

In the highest position of the double lever m (illustrated in the drawings by black lines) the dirt-removing rail t" is moved backward. When now the lever m is disengaged, the rail 1 is moved to the right, owing to the shaft g, the arm k, and the connecting-rod Z, and the ingredients located upon the comb h are removed from the same.

In order to attain a reliable contact of rail 4; with the surfaceof the comb h, this rail consists of two parts, as clearly illustrated in Fig. 3. To the rail 41 proper a second rail 2' is slidably attached by means of bolts 1J sliding within slots 11 of the rail 1''.

In Fig. 1, besides the dirt-removing rail 2',

a second rail r, shorter than the first one, is

arranged. This second rail sometimes can be of importancefor instance, for purifying the dirty water of sugar-factories, which very often contains pieces or tails of beet-root. In these cases the shorter rail 1" would remove the substances of large diameter,while the longer rail 2" removes substances of small dimensions. In the drawings two transporting-worms s s are arranged to conduct the dirt to any place desired. Evidently these worms can be replaced by transportbands or similar other arrangements. The suspending rods h for the dirt-removing rails e, as illustrated in the drawings, pass through sockets g in the shaft 9 and by means of screws g are adjusted and kept in position. This suspension offers the great advantage that when the rail 11 does not swing around in due time the comb simply raises the dirtremoving rail 2", whereby the rods h are moved upward and pass through their sockets g. Thereby no injuries may happen during the actuation of the apparatus. The before-deinto the grate and stop there.

scribed arrangement in most cases suffices to remove substances of a diameter not allowing their passing through the grates. Only in the purifying of certain dirty waterfor instance, Waste of sugarfactories-it may happen that sometimes tails of beet-root come Evidently the fibers or tails of beet-root are removed by the removing-railt"; butit may happen that some tails stop at the upper extremity of the grate. In order to prevent the accumulation of such objects, the same are cut by the mechanism, as illustrated in Figs. land 5.

1 represents the tail of a beet-root which has not been removed by the rails. A lever u is arranged upon a shaftt and carries a knife 4). The opposite extremity reposes upon a cam w and is weighted by a weight 00. At each revolution of the cam w this lever falls down, while the upper arm, with the knife, is pushed upward, thereby cutting the beetroot accumulated and allowing the dirt-removing rail t" to easily remove the substance from the grate.

Having thus fully described the nature of my said invention, what I desire to secure by Letters Patent of the United States is- 1.
